The exact number of same-sex married couples in the U.S. is unknown (the Census Bureau is still working toward making improvements to this measurement), but federal tax returns provide perhaps the closest estimation. After all, about 96 percent of married tax filers file jointly, according to the Tax Policy Center. A new report from the center estimates in 2015 — the year same-sex marriage was legalized across the U.S. — there were 250,450 same-sex married tax filers (about 0.48 percent of all married tax filers), up from about 131,080 in 2013 and 183, 280 in 2014 (when same-sex marriage was only recognized in some states).
"Same-sex joint filers are generally younger, higher income, less likely to claim dependent children (especially for male couples), and more geographically concentrated than are different-sex filers," according to the Tax Policy Center's new report.
While married same-sex couples tend to have higher incomes, the income of male couples was more than 40 percent higher than that of straight couples and female couples. The average adjusted gross income of male couples in 2015 was about $165,960, versus $118,415 for female couples and $115,210 for different-sex couples. Male same-sex couples with dependent children had an average income of $264,000, more than double that of female couples and straight couples with dependent children.
Same-sex couples, the report notes, are more likely to be of working age and to live in major metropolitan areas and coastal states where incomes and living costs are relatively high.
When the data broken down by state (and the District of Columbia), D.C. is the breakaway winner with same-sex couples making up 4.17 percent of all married couples, followed by Massachusetts and Vermont, which both came in at 0.99 percent. North Dakota came in last at 0.13 percent.
The report also broke down the data by city (technically U.S. Community Zones, or CZs) to find those with the largest share of same-sex married couples. Here's the report's top 10 list:
